Description

Technical Field

[0001] This utility model relates to the field of flat copper wire processing technology, specifically a cutting device for flat copper wire with four-sided chamfering function. Background Technology

[0002] Flat copper wire is widely used in the electrical industry due to its good conductivity, mechanical properties and thermal stability. However, cutting is a critical step in the processing of flat copper wire, and its quality directly affects the performance of subsequent processes and the final product. Therefore, it is of great significance to develop efficient and precise flat copper wire cutting devices.

[0003] A search revealed a utility model patent with Chinese patent publication number CN216881481U, which discloses a flat copper wire fixed-length cutting device, comprising: a longitudinal and transverse straightening mechanism installed on the feeding end of the machine body; a flat copper wire rolling servo traction mechanism installed on the middle part of the machine body for traction of the flat copper wire according to a set length value; an encoder detection mechanism for detecting the moving length of the traction flat copper wire; and a pneumatic shearing and pushing mechanism for cutting the flat copper wire and pushing the cut flat copper wire into the dropping groove of the flipping dropping mechanism.

[0004] The aforementioned device uses scissors to cut flat copper wires. However, after cutting, it produces flat cuts with chamfered edges on both sides, and some of the edges extend to both sides. When the flat copper wires are inserted into precision components such as stator slots, they may scratch components such as insulating paper, thereby affecting the overall quality and performance of the product. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for flat copper wire with four-sided chamfering function, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for flat copper wire with four-sided chamfering function, including a base plate, a cutting component and a leveling component installed on the top of the base plate, the cutting component and the leveling component being at the same level, the cutting component including a support plate fixedly connected to one side of the outer wall of the top of the base plate, two limiting grooves opened on the inner wall of one side of the support plate, a movable seat slidably connected inside each of the two limiting grooves, a cutting blade fixedly connected to the outer wall of the two movable seats that are close to each other, and the two cutting blades are each composed of four equally spaced blades.

[0007] As a further preferred embodiment of this technical solution, a drive rod is rotatably connected to one side of the inner wall of each of the two limiting grooves, and a connecting rod is rotatably connected to one end of each of the two drive rods. The ends of the two connecting rods that are close to each other are rotatably connected to the movable seat. Two sprockets are rotatably connected to one side of the outer wall of the support plate. The two sprockets are coaxially fixed to one end of the rotation shaft of each of the two drive rods. The two sprockets are fitted with the same chain. A motor is fixedly installed at the top of one side of the outer wall of the support plate. The output end of the motor is coaxially fixed to one of the top sprockets.

[0008] It can form a chamfered shape at the cut of the flat copper wire, thus creating a pointed tip, which is more convenient for later use and avoids the extended burrs from scratching the insulation paper. The motor on the outside of the support plate is started, and its output end drives one sprocket to rotate once. It drives another sprocket to rotate synchronously through the chain. In turn, the two drive rods are driven to shake synchronously. The moving seat, which is restricted by the limit groove, can only move up and down. Therefore, the drive rod drives the moving seat to move up and down once through the connecting rod. Then the two cutters will come closer to each other and squeeze the flat copper wire until it is finally cut. The cut of the copper wire will form a triangle, and the two sides at the corners will also form beveled chamfers. The two cutters work together to form a pointed tip with chamfered edges.

[0009] As a further preferred embodiment of this technical solution, the leveling component includes a mounting frame fixedly connected to the other side of the top outer wall of the base plate. A two-way lead screw is rotatably connected to the top and bottom inner walls and the inner walls at both ends of the mounting frame, and the two two-way lead screws are arranged vertically. A flat plate is threaded onto the threaded ends of the two two-way lead screws. Two limiting rods are fixedly connected to the top and bottom inner walls and the inner walls at both ends of the mounting frame. The two flat plates that are close to each other are slidably fitted onto the outside of two motors that are close to each other.

[0010] As a further preferred embodiment of this technical solution, two support rods are fixedly connected to the middle of the top outer wall of the base plate. The two support rods are rotatably connected to the same guide roller through a bearing. A sliding rod is fixedly connected to the top outer wall of each of the two support rods. A connecting seat is slidably sleeved on the outside of each of the two sliding rods. A pressure roller is rotatably connected to the two connecting seats through a bearing. A spring is sleeved on the outside of each of the two sliding rods. The two springs are fixedly connected to the support rod and the connecting seat, respectively.

[0011] The flat copper wire can be leveled before cutting, thus fixing the length of the cut wire. The positions of several leveling plates are adjusted according to the specifications of the flat copper wire. The two leveling plates, which are sleeved outside the two limit rods, can only move horizontally. Therefore, the two-way lead screw can drive the two leveling plates to move towards each other until the two sets of leveling plates can fit against the outer wall of the flat copper wire. The copper wire is then passed through the gap between the two sets of leveling plates and the guide roller and pressure roller. The pressure roller is lifted by the copper wire, and the reaction force of the stretched spring is applied to the copper wire through the connecting seat and the pressure roller. The guide roller is then driven to start conveying the copper wire. In this way, the copper wire can be continuously passed through the two sets of leveling plates and will be corrected to a flat state.

[0012] As a further preferred embodiment of this technical solution, a funnel-shaped guide bucket is fixedly connected to one side of the outer wall of the support plate, and the guide bucket is located between the two cutters.

[0013] As a further preferred embodiment of this technical solution, a guide groove is provided on both sides of the top outer wall of the bottom movable seat, and the two guide grooves are respectively located at the bottom of the notch of the bottom cutter.

[0014] As a further preferred embodiment of this technical solution, the outer walls of the two flat plates on one side that are close to each other are each connected to multiple rollers via bearings.

[0015] This utility model provides a cutting device for flat copper wire with four-sided chamfering function, which has the following advantages:

[0016] (1) By setting the cutting component, this utility model can form a chamfered shape at the cut of the flat copper wire, thus forming a pointed tip, which is more convenient for later use and avoids the extended burrs from scratching the insulation paper. Start the motor outside the support plate, and its output end drives a sprocket to rotate once. It can drive another sprocket to rotate synchronously through the chain. Then the two drive rods are driven to shake synchronously. The moving seat restricted by the limiting groove can only move up and down. Therefore, the drive rod can drive the moving seat to move up and down once through the connecting rod. Then the two cutters will approach each other and squeeze the flat copper wire until the flat copper wire is finally cut. The cut of the copper wire will form a triangle, and the two sides at the corners will also form a chamfered edge. The two cutters can form a pointed tip with chamfered edges.

[0017] (2) By setting up a leveling component, the flat copper wire can be leveled before it is cut, so that the length of the flat copper wire can be fixed. The position of several leveling plates is adjusted according to the specifications of the flat copper wire. The two leveling plates, which are sleeved outside the two limit rods, can only move horizontally. Therefore, the two-way screw can drive the two leveling plates to move towards each other until the two sets of leveling plates can fit against the outer wall of the flat copper wire. Then the copper wire is passed through the gap between the two sets of leveling plates and the guide roller and the pressure roller. The pressure roller is lifted by the copper wire. The reaction force of the stretched spring will be applied to the copper wire through the connecting seat and the pressure roller. Then the guide roller is driven to start the copper wire to be conveyed. Thus, it can continuously pass through the two sets of leveling plates, and the copper wire will be corrected to a flat state.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figure 2 and Figure 4As shown, the leveling component 3 includes a mounting frame 307 fixedly connected to the other side of the top outer wall of the base plate 1. A two-way screw 308 is rotatably connected to the top and bottom inner walls and the inner walls at both ends of the mounting frame 307, and the two two-way screws 308 are arranged vertically. A flat plate 310 is threaded onto the threaded ends of the two two-way screws 308. Two limiting rods 309 are fixedly connected to the top and bottom inner walls and the inner walls at both ends of the mounting frame 307. The two flat plates 310 that are close to each other are slidably sleeved on the outside of the two motors 209 that are close to each other.

[0026] Two support rods 301 are fixedly connected to the middle of the top outer wall of the base plate 1. The two support rods 301 are rotatably connected to the same guide roller 302 through a bearing. A slide rod 303 is fixedly connected to the top outer wall of each of the two support rods 301. A connecting seat 304 is slidably sleeved on the outside of each of the two slide rods 303. The same pressure roller 305 is rotatably connected between the two connecting seats 304 through a bearing. A spring 306 is sleeved on the outside of each of the two slide rods 303. The two springs 306 are fixedly connected to the support rod 301 and the connecting seat 304 respectively.

[0027] Adjust the positions of several flat plates 310 according to the specifications of the flat copper wire. Rotate the double-acting screw 308 by turning the knob. The two flat plates 310, which are sleeved outside the two limit rods 309, can only move horizontally. Therefore, the double-acting screw 308 can drive the two flat plates 310 to move towards each other until the two sets of flat plates 310 can fit against the outer wall of the flat copper wire. Then, pass the copper wire through the gap between the two sets of flat plates 310 and the guide roller 302 and the pressure roller 305. The pressure roller 305 is lifted by the copper wire. The reaction force of the stretched spring 306 will be applied to the copper wire through the connecting seat 304 and the pressure roller 305. Then, drive the guide roller 302 to start conveying the copper wire. In this way, the copper wire can be continuously passed through the two sets of flat plates 310 and will be corrected to a flat state.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the flat copper wire cutting device with four-sided chamfering function includes a base plate 1. A cutting component 2 and a leveling component 3 are installed on the top of the base plate 1. The cutting component 2 and the leveling component 3 are at the same level. The cutting component 2 includes a support plate 201 fixedly connected to one side of the top outer wall of the base plate 1. Two limiting grooves 202 are opened on the inner wall of one side of the support plate 201. A movable seat 205 is slidably connected inside each of the two limiting grooves 202. A cutter 206 is fixedly connected to the outer wall of the two movable seats 205 that are close to each other. Both cutters 206 are composed of four blades that are equally distributed.

[0029] A drive rod 203 is rotatably connected to one side of the inner wall of each of the two limiting grooves 202. A connecting rod 204 is rotatably connected to one end of each of the two drive rods 203. The ends of the two connecting rods 204 that are close to each other are rotatably connected to the movable seat 205. Two sprockets 207 are rotatably connected to one side of the outer wall of the support plate 201. The two sprockets 207 are coaxially fixed to one end of the rotating shaft of each of the two drive rods 203. The two sprockets 207 are fitted with the same chain 208. A motor 209 is fixedly installed on the top of one side of the outer wall of the support plate 201. The output end of the motor 209 is coaxially fixed to one of the top sprockets 207.

[0030] The motor 209 outside the support plate 201 is started. Its output drives one sprocket 207 to rotate one revolution. Through the chain 208, it drives another sprocket 207 to rotate synchronously. As a result, the two drive rods 203 are driven to rock synchronously. The moving seat 205, which is restricted by the limiting groove 202, can only move up and down. Therefore, the drive rod 203 can drive the moving seat 205 to move up and down once through the connecting rod 204. As a result, the two cutters 206 will come closer to each other and squeeze the flat copper wire until it is finally cut. The cut of the copper wire will form a triangle, and the two sides at the corners will also form beveled chamfers. With the cooperation of the two cutters 206, a pointed tip with four beveled sides can be formed.

[0031] like Figure 1 and Figure 5 As shown, a funnel-shaped guide bucket 211 is fixedly connected to one side of the outer wall of the support plate 201, and the guide bucket 211 is located in the middle of the two cutters 206. The driven copper wire first enters the port of the guide bucket 211, and then gradually moves to the middle of the two cutters 206 under its guidance, so that the cut is accurate enough.

[0032] like Figure 1 and Figure 5 As shown, a guide groove 210 is provided on both sides of the top outer wall of a bottom movable seat 205. The two guide grooves 210 are located at the bottom of the notch of a bottom cutter 206. The generated excess material will slide down and fall into the guide groove 210, and then fall into one place along the slope for easy processing.

[0033] like Figure 4 As shown, the outer walls of the two flat plates 310 on one side are rotatably connected by bearings to multiple rollers 311, which can transform the sliding friction between the copper wire and the flat plate 310 into rolling friction, making the movement of the copper wire easy.

[0034] This utility model provides a cutting device for flat copper wire with four-sided chamfering function. The specific working principle is as follows:

[0035] When the device is working, the positions of several flat plates 310 are adjusted according to the specifications of the flat copper wire. A knob drives the bidirectional lead screw 308 to rotate. The two flat plates 310, which are fitted outside the two limit rods 309, can only move horizontally. Therefore, the bidirectional lead screw 308 can drive the two flat plates 310 to move towards each other until the two sets of flat plates 310 can respectively adhere to the outer wall of the flat copper wire. Then, the copper wire is passed through the gap between the two sets of flat plates 310 and the guide roller 302 and pressure roller 305. The pressure roller 305 is lifted by the copper wire, and the reaction force of the stretched spring 306 is applied to the copper wire through the connecting seat 304 and the pressure roller 305. This drives the guide roller 302 to start conveying the copper wire. Thus, the copper wire continuously passes through the two sets of flat plates 310, and is straightened to a flat state. The conveyed copper wire first enters the guide hopper 211 port, and then gradually moves to the two cutters 206 under its guidance. The cut is made precisely in the center, ensuring a precise cut. The motor 209 outside the support plate 201 is activated, its output driving one sprocket 207 to rotate once. This, via the chain 208, drives another sprocket 207 to rotate synchronously. Consequently, the two drive rods 203 are driven to rock synchronously. The movable seat 205, restricted by the limiting groove 202, can only move up and down. Therefore, the drive rod 203, via the connecting rod 204, drives the movable seat 205 to move up and down once. This causes the two cutters 206 to approach each other, simultaneously squeezing the flat copper wire until it is finally cut. The cut of the copper wire will form a triangle, with beveled edges on both sides. The two cutters 206 working together create a pointed tip with beveled edges. Any excess material will slide down and fall into the guide trough 210, then collect along the slope for easy processing.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
